The Binomial Theorem: The Formula Purplemath
WebApr 8, 2024 · The formula for the Binomial Theorem is written as follows: ( x + y) n = ∑ k = 0 n ( n c r) x n − k y k. Also, remember that n! is the factorial notation. It reflects the product of all whole numbers between 1 and n in this case. The following are some expansions: (x+y)1=x+y. (x+y)2=x²+2xy+y². (x+y)3=x³+3x²y+3xy²+y³. (x+y)n.
